To find the box answer, you can divide y by x:

$\frac{y}{x}$

You can check every pair, bit I'm going to show you the first 2 as an example:

$\frac{ - 6}{ - 4} = \frac{3}{2} \\ \\ \frac{ - 3}{ - 2} = \frac{3}{2}$

So 3/2 is the answer!

Answer:

B Survey a random sample of eighth-grade students

Step-by-step explanation:

In order to reach the best conclusion without biased data, the best sampling method would be B because not only does it survey 8th graders, but it also surveys a random group, ensuring that not all of the students are potentially excelling in and/or having trouble with homework.

2. Two angle measures are in the ratio 5:9. Write

iris [78.8K]

The two angles are x and 9x/5

Let the two angles we require be x and y.

<h3 /><h3>Ratio of both angles</h3>

We have that the ratio of both angles are x:y

Since both angles are in the ratio 5:9, we have that,

x:y = 5:9

⇒ x/y = 5/9

<h3 /><h3>Value of the other angle</h3>

So, we Make y subject of the formula

Multiplying both sides by y, we have

y × x/y = 5/9 × y

x = 5y/9

Multiplying both sides by 9, we have

9 × x = 5y/9 × 9

9x = 5y

Dividing both sides by 5, we have

9x/5 = 5y/5

y = 9x/5

So, the two angles are x and 9x/5

How many solutions does the system have?<br> 3x + y = 8<br> 2 + 2y = 8

REY [17]

Answer:

x=2,y=2

Step-by-step explanation:

This question is a simultaneous equation

So let's solve

3x+y=8...(1)

2x+2y=8....(2)

Multiply (1) by 2

6x+2y=16...(3)

Substrate (2) From (3)

4x=8

Let's make x the subject of formula by dividing both sides by 4

x=2

So let's substitute the value of x into (1)

3x+y=8

3(2)+y=8

6+y=8

y=8-6

y=2

Therefore x is 2,y is 2

HELP!!!!!!!!What is the equation, in slope-intercept form, of the line that passes through (0, −2) and has a slope of −3?

emmainna [20.7K]

Answer:

y= -3x -2

Step-by-step explanation:

(0 , -2) and a slope of -3

The -2 is the y-intercept, put the initial point there

Use that point and put the -3 slope

How to Answer this i dont know please like it was not in the book im so confused

The solution to the system of inequalities given is: $\frac{4}{3} \leq y \leq 4$

<h3>What is the solutions to a system of inequalities?</h3>

The solution is the set of values that respect all conditions of the system.

The first condition is:

$3y - 13 \geq -9$

$3y \geq 4$

$y \geq \frac{4}{3}$

The second condition is:

$3y - 13 \leq -1$

$3y \leq 12$

$y \leq \frac{12}{3}$

$y \leq 4$

The intersection of the conditions, which is the solution to the inequality, is:

$\frac{4}{3} \leq y \leq 4$
